For Nori Croquant:
Grind nori in a spice grinder. Add neutral caramel to ground nori
in a 4:1 ration and grind to a powder. Do not over-grind or the
mixture will clump. On an inverted sheet pan, place a silpat and
spray with non-stick cooing spray. Sift sugar nori mixture onto
silpat over template. Warm in oven just until set. Allow to cool
slightly, and then remove croquant from sheet pan.

To Assemble and Serve:
Fill nori croquant with wasabi foam and pin to close. Top urchin
with croquant. Garnish with red shiso, chives and lemon zest
